Our Mission
We built DateTools.live to make everyday calendar math effortless. Whether you’re planning a project timeline, verifying a “3–5 business day” estimate, or calculating your age down to days, our tools are designed to be simple, accurate, and instantly accessible.
Privacy by Design
Most calculators on DateTools.live run entirely in your browser. We do not ask you to create accounts, and we do not store your calculator inputs (such as birthdays, work hours, or date ranges).
We use analytics only to understand overall usage trends (for example, which pages are popular) and only after consent is provided through our Consent Management Platform.
Built for Speed
The website is fully static and optimized for performance. Pages load quickly worldwide thanks to a global CDN. We keep the experience lightweight, with minimal dependencies and clean UI patterns.
Who This Is For
- Project managers planning milestones, timelines, and delivery dates
- HR and payroll teams tracking hours and business-day ranges
- Students and researchers working with historical and future dates
- Anyone who wants accurate answers without spreadsheets
Feedback & Improvements
DateTools.live is actively improved. If you have a feature request or notice something that could be clearer, we appreciate your feedback—small improvements compound into a better toolset for everyone.
